Increasing the length of a frame and push following strips
I just discovered the sequence "Shift-K", "A", "E", "G" :)


Position cursor on the frame you want to make a still from
Hard cut (Shift-K)
Go to next frame
Hard cut (Shift-K)
Go to previous frame (cursor left)
Extend from frame (E) &lt;-- This does the trick!
Grab the remainder and move it as far right as you'd like
